| Uca (Minuca) burgersi Holthuis, 1967 was studied in the laboratory under the morphological and systematical stand points. One experiment was carried out involving 100 larvae, derived from one ovigerous female collected in the north coast of the State of São Paulo, Brazil. The experiment were carried out in a climatically controlled room at 25±1ºC and steady saltness of 34 The larvae were maintened individually and food consisted of rotifers (Brachionus plicatillis) in the first stage and Artemia sp. in the last stages. Uca (Minuca) burgersi have five or six zoeal stages and a megalopa one. All larval stages were drawn and described in detail. Tables where the morphological characteristic of each stage of the studied specie was described are also included.... |

| Durante os anos 2000 e 2001 foram realizadas coletas sazonais de crustáceos decápodes em dois pontos de um rio na Estação Ecológica Juréia-Itatins, utilizando-se duas metodologias distintas (peneira e armadilha). Comparando-se ambos os métodos de coleta, foram constatadas diferenças quanto à composição e riqueza da carcinofauna capturada, grau de dominância e equitatividade, bem como tamanho e número de indivíduos coletados. Além disso, as razões sexuais de Macrobrachium acanthurus (Wiegmann, 1836) podem diferir dependendo do método de coleta utilizado. Devido à grande variedade de hábitats e hábitos dos crustáceos, pode-se inferir que, para um levantamento qualitativo e/ou quantitativo eficaz e apurado da comunidade de crustáceos decápodes dulcícolas de... |

| The Brachyura collected on the continental shelf of Northern and Northeastern Brazil understood between the latitudes 4º27'N and 3º43'S and the longitudes of 50º00'W-38º00'W, were represented by 133 species, 79 genera and 15 families. The studied material, belongs to the carcinological collection of the Department of Oceanography of University Federal of Pernambuco. The informations obtained in relation to the areas in which these species are found, were gathered from the carcinological files cited above and bibliographic rcferences published until 1991. The majority of the species (125) was found exclusively in the western Atlantic, except three Anfi-Atlantics, two Anfi-Americans, two Circuntropicals and one Indo-Pacific. With regards to the latitude, 11... |

| Marine deposits of the Neuquén Basin of west-central Argentina (southern South America) are richly fossiliferous; its Mesozoic invertebrate faunas, represented mostly by molluscs, have been extensively studied since the nineteenth century. However, Early Cretaceous decapod crustaceans are far less known, although part of the systematic framework has been published (Aguirre-Urreta, 1989). The aim of the present note is to provide updated information based on ongoing research into the systematics and taphonomy of this crustacean group in the Neuquén Basin. |

| Recently discovered crabs from the Middle to Upper Eocene of northern Bonaire, Netherlands Antilles, include well-preserved carapaces of Montezumella rutteni Van Straelen, originally described from an incomplete holotype. The more comprehensive description of this species provided herein includes documentation of the first attributable left cheliped of Montezumella. From the same locality, Ocalina sublevis sp. nov. considerably extends the known geographic range of this genus. Both of these Tethyan decapod genera apparently migrated west from the Mediterranean region during the Eocene. Despite these new determinations, decapod crustaceans remain poorly known from the Eocene of the Antillean islands. Additionally, Callianassa pustulosa Withers from the... |

| Gastropod shells occupied by hermit crabs are an important attachment substrate for epifauna, and these shells are often damaged. The present study aimed to characterize the epibionts and extent of damage for gastropod shells occupied by the hermit crab Loxopagurus loxochelis (Moreira, 1901). Samples were collected monthly over a period of one year (from July 2002 through June 2003), in the Caraguatatuba and Ubatuba regions, on the northern coast of São Paulo, Brazil. The sampling was performed using a fishing boat equipped with double-rig nets. The shells were identified and weighed. Loxopagurus loxochelis occupied 14 gastropod shell species in Caraguatatuba and five in Ubatuba. In the two areas, approximately 55% of these gastropod shells bore epibionts,... |

| The project PRS-GEDIP was carried out in the Rio Grande do Sul coast, with some few stations off Maldonado (Uruguay), by means of a convention between Instituto Oceanográfico USP (IOUSP) and the Grupo Executivo do Desenvolvimento da Indústria da Pesca (GEDIP) of Rio Grande do Sul. The purpose of this project was the acquisition of data in order to have a better biotic and abiotic characterization of the southern Brazilian coast. Among the Galatheidae, about 1200 specimens of the genus Munida Leach, 1820 were collected, including five species as follows: Munida flinti Benedict, 1902; M. forceps A. Milne Edwards, 1880; M. iris A. Milne Edwards, 1880; M. irrasa A. Milne Edwards. 1880 and M. longipes A. Milne Edwards, 1880. The description, material examined,... |

| La fauna de crustáceos malacostráceos limnéticos, en el territorio de Chile continental, está compuesta por seis especies de camarones, i.e., cinco parastácidos de los géneros Parastacus, Samastacus y Virilastacus y un palemónido del género Cryphiops, 18 especies de anomuros del género Aegla, siete especies de anfípodos gamarídeos del género Hyallela y una especie de isópodo aselotano del género Heterias. La distribución conjunta abarca desde Arica a Punta Arenas, pero la mayor parte de las especies tiene rango geográfico restringido. La mayor densidad de taxa ocurre entre las regiones VIII y X, donde el número de taxa por Región varía entre 11 y 15, siendo la X Región la que tiene el número mayor. Índices derivados de un estudio sobre relaciones... |

| The crustaceans from the marine Berivotra Formation, dated as late Cretaceous, from 50 km south of Mahajanga, Madagascar contains macrurans, brachyurans and thalassinideans. Two brachyuran families, Raninidae and Dynomenidae, were previously identified with the genera Notopocorystes, Caloxanthus, Titanocarcinus, Xanthosia, and Dromiopsis. Fragmentary material now also allows the recognition of Dromioidea, Calappoidea and Xanthoidea. |

| We record the discovery of Coleia Broderip (Eryonoidea: Coleiidae) from the Nakatsuka Formation, Mine Group, Upper Triassic of Japan. The specimens were collected from shales exposed at Tsubuta, Sanyo-cho (Yamaguchi Prefecture). Coleia co-occurs there with fragments of a penaeoid, bivalves, Halobia spp., ammonites, and plants. |

| A study of the annual abundance fluctuation, temporal distribution and size composition of Aegla castro Schmitt, 1942 was carried out at the Buraco do Padre, Quebra-Perna River, Tibagi River Basin, in the municipality of Ponta Grossa, Paraná State. The samplings were done monthly, from February/97 to January/98 with the aid of a hand net and screens at three stations, under an effort of 120 minutes. The average air temperature ranged from 15.0ºC (May, July, September and October) to 24.3ºC (December and January), and the water temperature from 15.8ºC (July) to 22.3ºC (December). The dissolved oxygen oscillated from 95.7% (March) to 100. 2% (August) saturation, and the pH from 6.1 (July) to 7.2 (September). The water flow speed varied from 0.2 m/s to 1.2... |

| A new genus of parthenopid crab, Garthambrus gen. nov., characterised by a broad carapace with strongly raised branchial and gastric regions, distinctive rostrum, sub-cylindrical ambulatory meri and a long distal segment of the second male pleopod, is established for six deep water species from various parts of the Pacific. A new species, Garthambrus posidon spec, nov., is also described from depths of between 480 to 600 m off the Seychelles in the Indian Ocean. It differs from its closest congener, G. poupini (Garth, 1993), in having a proportionately broader carapace, less granulated carapace and chelipedal surfaces, and in the form of the carapace regions. |
